有什么方法可以检测驱动器是否为SSD? [英] Is there any way of detecting if a drive is a SSD?

问题描述

我准备发布仅对常规硬盘有效，而对SSD(固态硬盘)无效的工具.实际上，它不应该与SSD一起使用，因为它会导致大量读/写操作而没有实际效果.

I'm getting ready to release a tool that is only effective with regular hard drives, not SSD (solid state drive). In fact, it shouldn't be used with SSD's because it will result in a lot of read/writes with no real effectiveness.

任何人都知道一种检测给定驱动器是否为固态的方法吗?

Anyone knows of a way of detecting if a given drive is solid-state?

推荐答案

检测SSD并非像dseifert指出的那样简单. linux的libata已经有了一些进步( http://linux .derkeiler.com/Mailing-Lists/Kernel/2009-04/msg03625.html )，尽管它似乎尚未为用户所用.

Detecting SSDs is not as impossible as dseifert makes out. There is already some progress in linux's libata (http://linux.derkeiler.com/Mailing-Lists/Kernel/2009-04/msg03625.html), though it doesn't seem user-ready yet.

我绝对理解为什么需要这样做.基本上，这是链表和数组之间的区别.碎片整理通常在SSD上适得其反.

And I definitely understand why this needs to be done. It's basically the difference between a linked list and an array. Defragmentation and such is usually counter-productive on a SSD.
